To be small, it has non-standard pin size separation, it is not 0.1" (not compatible with breadboards, etc).

excellent development board for applications where you want to connect to a home network. can be programmed with the Arduino IDE. I use it to make home automation and IoT application. with the application ara android Blynk can create dashboards very simply to command and monitor the board.

Good thing is that it is quite small WiFi module and can be fitted inside small boxes with Arduino board. Works fine. It's not hard to find pinout and schematics on the internet.

Suggestion:

You need to solder all the pins. It's quite sensitive job nad should not be done by people without good soldering knowledge.

Easy to use, many tutorials online, lots of fun for arduino enthusiasts, just had to buy an adapter plate to be able to play with breadboard.
